摘　　要：在不同结构的油区模型上，测量了线饼的温度分布，阐述了油区饼数、油道高度、油道尺寸分布对线饼的平均温升和热点温升的影响，分析了油区内油的流动情况和传热特性。The temperature distribution of disks of transformer winding is measured on the oil region models of different structures. The effects of disk numbers in oil regions, the height and the dimension distribution of oil duct on the average and hot-point temperature-rise of the disks are presented. And the oil flowing and heat-transfer performance in the oil regions are analysed.
